Abstract

Pour améliorer la sécurité et l'efficacité d'un système de changement de couleur, il est proposé d'actionner une vanne de milieu (3) par air comprimé. L'alimentation en air comprimé ne peut se faire que lorsqu'un stator (1), dans lequel les vannes de milieu (3) sont situées, est en contact avec une tête de sélection (2). En outre, un clapet anti-retour (10) est situé à l'entrée de milieu (8) de la tête de sélection (2), lequel clapet anti-retour se ferme lorsque le stator (1) et la tête de sélection (2) se trouvent à une distance l'un de l'autre pour effectuer un changement de vanne de milieux (3). Pendant cette période de changement, un liquide de rinçage peut être introduit dans le conduit de milieu (7) par un conduit de rinçage (11).
